From 677bfb0881c56dad767a07b31ac543db284e16c6 Mon Sep 17 00:00:00 2001 From: rpj Date: Thu, 14 Jan 1999 22:33:54 +0000 Subject: Fri Jan 15 15:41:28 1999 Ross Johnson * pthread.h: Add new 'abstime' arg to pthreadCancelableWait() prototype. * condvar.c (cond_timedwait): New generalised function called by both pthread_cond_wait() and pthread_cond_timedwait(). This is essentially pthread_cond_wait() renamed and modified to add the 'abstime' arg and call the new _pthread_sem_timedwait() instead of sem_wait(). (pthread_cond_wait): Now just calls the internal static function cond_timedwait() with an INFINITE wait. (pthread_cond_timedwait): Now implemented. Calls the internal static function cond_timedwait(). * implement.h (_pthread_sem_timedwait): New internal function prototype. * misc.c (pthreadCancelableWait): Added new 'abstime' argument to allow shorter than INFINITE wait. * semaphore.c (_pthread_sem_timedwait): New function for internal use. This is essentially sem_wait() modified to add the 'abstime' arg and call the modified (see above) pthreadCancelableWait(). --- pthread.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'pthread.h') diff --git a/pthread.h b/pthread.h index 455cf19..861a0e8 100644 --- a/pthread.h +++ b/pthread.h @@ -918,9 +918,10 @@ int pthread_attr_setschedparam (pthread_attr_t *attr, * WaitForMultipleObjects * * on 'waitHandle' and a manually reset WIN32 Event - * used to implement pthread_cancel. + * used to implement pthread_cancel.
